Answer: fluffy = 33yrs
Spot = 19 yrs
Skampy = 39 yrs
Step-by-step explanation:
Let fluffy = x
Spot = y
Skampy =z
x + y + z = 91 -------1
x -14 =y ------2
z = x + 6 --------3
Put eqn 2 and 3 in eqn 1
x + x - 14 + x + 6 = 91
3x = 99
x = 33
y = 33-14= 19
z = 33+6 = 39
2(3x-5) + 2(-2x+10)
6x-10 + -4x+ 20
=2x+ 10
Is 19:17 because u have to value the number of the first like this 78:807y :997
